T 0 all whom it may concern Be it known that I, JOHN V. MoMANIs, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Operating- Tables, of which the following is a specification.

The invention relates to operating tables to be used in giving movement cure treatments by osteopathic practitioners or for use by surgeons and others. The primary obj ect of the invention is to provide in a table of the described character certain structural improvements hereinafter shown and de scribed and particularly pointed out in the claims.

Fig. 12 is a longitudinal sectional view approximately on line 1212 of Fig. 11, the view also showing a portion of the supporting structure in section.

In a treating or operating table of the class to which my invention belongs, it is desirable that the structure permit of a multiplicity of adjustments and movements securing ease of manipulation for curing and treating physical irregularities of the spine and other bony portions of the human body.

In the embodiment of the invention shown in the drawings, the preferable form of supporting means for the table top is a pedestal (see Fig. 1) having a rigid extended base portion indicated by the reference character 10 and an upright portion. which may be in the form of a cylinder as indicated by reference character 11. The portion 11 of the pedestal preferably takes the form. of a cylinder for receiving a piston or plunger on the cooperating member 12 supporting on its upper extremity the table top. An adjustable connection between member 12 and the portion 11 of the pedestal is preferably provided in the form of a hydraulic lifting means of any desired or common construction not herein shown with the exception of operating lever 13 pivoted to the member 12 at 14 (see Fig. 11) and having a pivotal connection at 15 with a member 16 comprising a portion of the hydraulic mechanism. 17 is a screw threaded locking member supported in the threaded extension ll which is adapted to cause the shoe 18 to be forced against the supporting standard or lunger 12, either to lock the same in an a justed position or to exert a braking effect on the plunger. An irregularly formed member 12 is rigidly secured to the upper extremity of the standard or plunger 12 and has a depending branch 12 in the form of an elongated hollow bearing member which serves to pivotally support a portion of the table top as hereinafter described. On the opposite extremity of member 1.2" or at an angle of 180 degrees from the pro,- jection 12 is a radial projection 12 to which the parallel supporting rods 19 and 20 are secured by suitable bolts or machine screws as indicated at 21. The rods 19 and 20 thus rigidly secured to the extension 12 of the standard 12 are designed to furnish a support for the main table top section which is indicated generally by the reference character 22. In a table designed to manipulate various portions of the frame of the human body as practised by the osteopathic profession I have found that it is a decided advantage to be able to give the main table top section two distinct movements in addition to the raising and lowering thereof in vertical planes. These movements are, first, a rocking or canting movement preferably on the longitudinal axis of the table, and second, a longitudinal movement of the main table top on av horizontal plane toward or away from the other two sections of the table top. The small middle section which I mount intermediate the main top sections, is designated by the reference character 23, and the section which I call the auxiliary table section, is designated by the reference character 24 (see Figs. 1 and 2). When the main table section 22 is moved so as to separate or move away from the intermediate sections 23 and 24C of the table top, if the body of the patient be secured by straps or other suitable means to the relative portions it will be seen that by such separation a stretching action of the body and frame of the patient may be secured, and hence the longitudinal movement of the main table section is hereinafter referred to as the stretching movement of this section of the table top. This stretching movement as well as the canting or rocking movement of the main table section. referred to is provided for by the connection with the supporting members 19 and 20 which is as follows:

Mounted on the parallel rods 19 and 20 carried by the pedestal are three triangular shaped supporting brackets designated by the reference characters 25, 26 and 27. The shape of these brackets is best shown by reference to views shown in Figs. 4c and 5 from which it will be seen that each of the brackets is mounted upon rods 19 and 20 of the frame near the outer extremities of the brackets while at the vertex of these brackets openings are made for passing therethrough the adjusting rod 28 which has a crank at its outer extremity as indicated by 28 and passing through a bearing member 29 secured to the under side of the main table section. To prevent endwise movement of the threaded adjusting and operating rod 28, in relation to main table section 22, collars as indicated at 30 are secured to the rod 28 on each side of the bearing block 29 (see Figs. 1 to 3 inclusive and Fig. 11). The rod 28 is further supported on the main table section 22 by the bearing members 31 and 32 secured to the main table top. In order to enable the main table top 22 to be adjusted by the manipulation of rod 28, the rod is threaded for a portion of its length, and the supporting member 25 is screw threaded to cooperate with the rod 28 and is fixedly se cured to the parallel rods 19 and 20 of the supporting frame by means of set screws as indicated by 25 Fig. 1 or other suitable means. The triangular bracket 26 supports the rod 28 and is provided with a set screw 26 bearing against the shoe 26 which is in contact with the rod 28 -(see Fig. 5). Ad-

justment of the set screw 26 may be resorted to to bind the shoe 26 in contact with the ad justing rod 28, to secure it in its adjusted po sition when desired, or by a slight adjustment of this device any desired kind of breaking eifect of the screw threaded rod 28 may be secured. The bracket 27 may be supported on the rods 19 and 20 and on the adjusting shaft 28, while the end of the shaft 28 remote from the crank portion 28 finds a bearing in bracket 32 which is secured to the underside of the main table section 22. From the construction described it will be seen that a stretching movement may be imparted to the main tab-1e section by manipulating the crank 28 of the rod 28 in the proper direction by which the threaded portion of the rod passing through relatively stationary bracket 25 will operatively engage and shift it, while the rotation in the reverse direction of the threaded rod 28 will restore the main table section to the normal position. With respect to the canting or rockng motion of the main table section 22, it will be seen that this section is supported on an axis consisting of the rod 28 which will permit the main table section 22, in the absence of other supporting means, to rock from side to side until portions thereof contact with the supporting brackets 25, 26 and 27, which are given a. pointed shapeto permit of this rocking or canting movement. Provision is made for rigidly securing the main table section 22 on its longitudinal axis and this consists of a pivoted lever 35 (see Figs. 1, 2, 3 and 5). The lever 35 is provided with a branch U shaped depending member 36 which normally rests in a position to pass by the bracket 26, as the main table top 22 is rocked or canted. The pivotal connection at 35 however will permit the lever 85 to be moved to a position where the depending members 36 will rest upon the top of the triangular shaped bracket 26 in the manner shown more clearly in Fig. 5, for locking the table top 22 against any canting or rocking movement on the axis rod 28.

One of the important features of my invention resides in the construction of the auxiliary table section and the means by which it is supported in resilient suspension from the table top supporting means 12 through the depending branch 12 heretofore referred to, which is provided with journal hearings to support the upright shaft 10 Figs. 1, 2, 3, 6, 7, 11 and The shaft or spindle 40 is provided with any suitable means as collar 41 by which it is rotatably supported in the bracket 12 against a downward movement beyond a predetermined limit. Rigidly secured to the upper extremity of the shaft 40 is an irregular shaped bracket 42 extending crosswise of the table top and being provided with ears as indicated by 42 (see Fig. 7) adapted to take the hinge pins 43 which pass through ears or hinged members 44 secured to the underside of the auxiliary table section 24. Rigidly secured to the lower extremity of the shaft is a block 44 to which is pivotally secured two parallel arms 45, 46 (see Figs. 1, 2, 6 and 9). The members 45 and 46 extend approximately parallel to the auxiliary table section 24 as will be seen from Fig. 1, and the connection between the outer extremities of these members and the auxiliary table section is secured through a link pivoted at one extremity to the members at 47 and at its other extremity to the underside of the table top at 48, the latter being a pivot pin passing through a suitable opening in the upper end of the link and the ears of a bracket 49 secured to the underside of the auxiliary table section 24. The link last referred to (see Fig. 10) is a composite member for purposes of adjustment and is preferably comprised of the screw threaded rod 50 which cooperates with an internally threaded tubular member 51. 52 is a threaded locking member for securing the rod 50 in adjusted relation to the tubular member 51. The tubular member 51 is surrounded by a sleeve 53 held in position thereon by abutting against a shoulder 51 and a hand operated screw threaded locking member 54 threaded on the upper extremity of the tubular member 51. Secured by screw thread ing or otherwise to the lower extremity of the tubular device 51, 53 is a member 55 having two depending branches spaced apart a sufficient distance to engage the opposite inner surfaces of the parallel bars 45, 46. Between the branches of the part 55 is a block 56 held in position by the pivot pin 47 and having one end of a threaded rod 57 journaled in a non-threaded opening therein and held against longitudinal movement with relation to the block 56 by a collar 57 secured thereon, there being a hand wheel 57 on the outer exposed end of the rod 57 for rotating it. The threaded rod 57 engages a cotiperating threaded block 58 slidingly mounted on spaced bars 45, 46 and being secured to one extremity of a relatively powerful coiled spring 59 secured by the eye 60 at its other extremity to the auxiliary table top 24. The function of the spring 59 is to resiliently sustain the auxiliary table top 24. A bar 61 is pivotally connected at 62 to a bracket 63 secured to the underside of the auxiliary table top 24, and at its lower extremity passes through an elongated slot formed by the keeper bar 64 spaced apart and secured to the bar 46 by the pivot bolt 47 and the spacing member or washer 65. As a means for adjustably securing the keeper bar 64 into locking relation, the other end of the keeper bar 64 is adapted to take a threaded bolt 66 secured to the bar 46 and having a Winged nut 67 by which a clamping action between the parts 46 and 64 may be exerted to hold the bar 61 and consequently the parts connected therewith and controlling the auxiliary table section 24 in their adjusted positions.

Details of the construction of the intermediate table section 23 and its controlling dcvices will now be described.

In the top plan View of the various sections of the table-top shown in Fig. 2 the construction of the intermediate table sec tion 23 and the cooperating main and auxiliary table sections is clearly shown, and from which it will be seen that the inside end of the main table section is cut in the form of a send-circumference to accommo date the convexly curved intermediate section 23 which latter is in the form of a half circle, being hinged along its diameter to the table top section 24, there being three of these hinges as indicated by the reference character 70 shown on Fig. 7 This hinge connection between the intermediate semi-- circular leaf 23 and the auxiliary section 24 will obviously permit relative movement between the two sections along the axis of the hinge connections, first, to permit the auxiliary section to be elevated or depressed independently of the intermediate section and second to permit raising and lowering of the intermediate section within certain limits on hinge connection 70. Inasmuch as intermediate table section is thus positively connected with the auxiliary section 24 and will move therewith when the auxiliary section is oscillated or vibrated on the axis pin 40 in a horizontal plane the circular cut in the end of the main table top 22 and the corresponding circular shape given to the intermediate section 23 are essential to permit freedom of movement as described.

Under some conditions it is found that to allow the intermediate table section 23 to remain in the elevated position, that is in the plane of the table sections 22 and 24, will result in contact of the section 23 in an objectionable manner with the body of the patient, and tend to chafe the same. For this reason I provide means for lowering or depressing the intern'iediate section 23 on the axis of its hinged connect-ions 70 with the auxiliary table section, when it is desired to operate the auxiliary table section with the intermediate section thus depressed. The bracket 42 secured to the shaft 40 and supporting the hinged auxiliary section 24 is provided with one or more branches or projections indicated by the center projection 42 and the end projections 42. These projections are beveled along their upper edges to permit the intermediate table section 23 to be dropped below the normal plane of the said section 23 and the normal plane of sections 22 and 24. This dropping movement of the section 23 is a swinging movement on the hinges 70 and is under the control of the operator at the side of the table top through a crank member the shaft of which is indicated by the reference character 7 5, the same being journaled on the under sides of the extensions 42 and 42*. An adjusting handle or arm is formed on the shaft 7 5 as indicated by the reference character 76, and at its opposite extremity the shaft 75 is provided with a crank arm or angular portion 77 terminating in a crank pin indicated by the reference character 78 (see Figs. 7 and 11). The crank pin 78 is in an engagement with the spaced plates 7 9 and 80, (Fig. 8) the latter of which is secured to slide loosely on pins or screws 81, 82, which pass through openings in said plates 7 9 and 80 and are secured into the body of the intermediate leaf 23 and on the underside thereof. The plate 7 9 is preferably provided with a depending flange along one edge furnishing a sort of a housing for the crank pin 78, as indicated by 79 and springs 84 hold plate 80 against the crank pin.

In Fig. 1 showing a side elevation view of my complete table upholstering or padding is indicated by dotted lines as being secured to the upper side of the main auxiliary and intermediate table sections. Any sort of material of sufficient resiliency to furnish protection to the body of the patient may be employed, and forms no part of the invention herein.

Generally speaking the operation of my improved table is about as follows:

The patient is placed in position lying flat upon the fiat table top formed by the main, auxiliary and intermediate sections with that portion of the body or frame of the patient into which it is desired that flexing or moving of the joints shall be secured. A portion of the body of the patient may for an example be strapped or otherwise secured to the main table section 22, and by swinging the auxiliary and intermediate table sections on the vertical axis 40 hold ing another portion of the patients body more or less securely on these table sections would result in a flexing or moving of one portion of the patients frame or skeleton in relation to the parts secured to the main table section 22. When it is desired to have the table sections 22, 23, and 24 all lying in the same plane and rigidly held in such plane, this may be accomplished by manipulating the operating handle 7 6 which will elevate and retain or lock the intermediate table section 23 in its elevated or normal position, shown in Fig. 1. At the same time the operator may prevent any vibrating or swinging movement in a horizontal plane on the axis pin 40 of the auxiliary and intermediate table sections 24 and 23 respectively by operating the hand wheel of the screw 83 (see Figs. 1 and 6). The screw 83 which is threaded in the depending branch 12 by contact at its inner extremity shaft 40 it will be obvious that the auxiliary I and intermediate table sections may be swung in horizontal planes from side to side on the axis shaft 40 and that the operator may by manipulating rod 57 shift the spring block 58 backward and forward between the parallel. bars 45, 46 thus varying the leverage to be exerted upon the spring 59 when the auxiliary table top is depressed, on its hinged connections at its outer or free end. This adjustment obviously will enable the operator to vary the carrying capacity of the auxiliary table within certain limits while the adjustment already referred to provided in the compound connecting rod details of which is shown most clearly in Figs. 1, 6, 9 and 10, may be employed to secure a further range of adjustment in the elastic carrying capacity of the auxiliary table section.

For the purpose of setting up resistance to lateral movement of the auxiliary or swinging table section 24 and the inter mediate section 23 hingedly connected thereto, I prefer to provide elastic means in the form of a tension spring 41 (see Figs. 1, 7 and 12). This tension spring is secured at one end to a projection on the collar 41 rigidly secured to the vertical shaft 40 carrying both table sections 23 and 24 and the other end of the spring is adjustably secured by means of a threaded eye-bolt 41 to a clip 41 fixed to the frame member 12. This construction, it will be seen, will cause the tension of spring 41 to be exerted whenever the vertical shaft 40 is rotated, and will tend to hold the table sections 24 and in the normal extended positions shown for example in the top plan view Fig. 2.

In addition to the binding screw 83 which may be used to lock the vertical shaft 40 against rotation, I provide a locking device shown in Fig. 2 which may be used also for locking the auxiliary and the intermediate table sections 23 and 24 against horizontal rotation on the axis 40, or, in other words. may lock the intermediate section 23 to the main table top section 22 when the intermediate section 23 is in its elevated posi tion flush with the plane of the sections 22 and 24.

This device is shown in Fig. 2, and consists of plunger or pin 100, slidably carried by clips 102 on the under side of the table section 22, and controlled by a spring 101 adapted to force it normally toward the intermediate section 23 to engage in an opening between the clip 103 and the intermediate section 23, thus efiectively lockin the sections 22 and 23 together.

hould the intermediate table section 23 tend to rub or abrade the body of the patient or otherwise annoy, the o erator, by manipulating the hand lever 6 in the manner already described, may allow the intermediate table section 23 to drop downwardly on its hinges, as indicated in Fig. 12, in which position it will be throughout most of its surface, considerably below the auxiliary and main table sections.

A stretching movement is obtained by securing different portions of the patients body to the intermediate and auxiliary table sections and to the main table section 22 and then operating the hand crank 28 which will cause the main table section to be drawn apart from the intermediate section 23 sliding on the supporting rods .19 and 20 through its connections in the manner already described. If it is desired to give a twisting movement on the longitudinal axis of the table top 22 this may be secured by fastening the patients body to the inter-- mediate and auxiliary table sections in their stationary positions and releasing the projections 36 on the lever 35 from contact with the bracket member 26, which will permit the main table section 22 to swing on the shaft 28 in the manner already described and subject to the adjustment of set screw 26 and the adjustable bearing shoe 26 which cooperates with the adjusting rod 28.

From the above description it will be seen that the construction of my improved table is such that the table is adapted to the securement of a great variety of swinging and twisting movements between various portions of the human body when placed there-. on in various relations thereto, and the invention is found admirably adapted, as already stated, for the use of Osteopaths and other persons practising movement cures of the various kinds in the difierentrschools of medicine and surgery.

While I have shown the invention and specifically described it in the embodiment of the invention preferred by me, I do not desire to be limited to the exact details shown, because it is apparent that persons skilled in this art may resort to various modifications without departing from the purpose and spirit of my invention.

In order that the invention might be understood the details of the preferred em bodiment of my invention have been shown and described, but it is not desired to be limited to the details referred to, for it will be apparent that persons skilled in the art may employ variations in the arrangements of the structure without departing from the purpose and spirit of the invention.
